"If I had known-" Youko started, but Kurama shoved him back.
"You're right. I hadn't even considered the possibility of Yukimura until this one ran off to find you. As soon as we realized was was going on, we split up to find him. Kuro and I did, I mean." He glared at Youko pointedly, and his demon half had the grace to shut up on this point.

Kurama held the look, then grimaced apologetically at Kusuriyuri. "I'm sorry, Koi. If I'd known this would happen..." he let the sentence hang. He just had a way with ruining his own life, didn't he.
